onsemi’s NCL2801 current mode CRM boost PFC control IC is key to the solutions that will be shown this year. This innovative device provides best-in-class total harmonic distortion (THD) over an extended operating range utilizing onsemi’s THD enhancer technique.
Working with PCB transformer manufacturer Itacoil®, onsemi has enhanced NCL2801LED2GEVB, a 150 W deep dimming LED driver evaluation board, without the need for expensive magnetic materials. Compared to the original evaluation board, the footprint of the inductive components has been reduced by 50% and its volume by 64%. The size of the evaluation board has also been reduced by 25% in footprint and 30% in volume. Electromagnetic compatibility (EMC) and electromagnetic interference (EMI) has been enhanced to achieve full compliance with EN50155. Efficiency has also improved, depending on the input voltage and operating power, from 0.3% up to more than 2%.
Another demonstration based on the NCL2801 and NCP13992 – a high performance current mode resonant converter controller that is primarily tailored for half bridge applications – will also be shown at the booth. The board is highly efficient due to its use of current mode LLC resonant operation, allowing 150 W output power to be delivered without the need for any form of heatsinking. The low-profile form factor is achieved using gallium nitride (GaN) technology, allowing efficiencies in excess of 94%, while consuming less than 300 mW when in standby mode.
